US 10,319,536 B1 · High-capacity electrical energy storage device

Abstract

A high-voltage energy storage device comprising at least one capacitor of any type, a main power source providing a high voltage to the electrodes of the capacitor either directly coupled or attached during charging of the high-capacity electrical energy storage device, and a secondary low-voltage power source providing an amplified high voltage to the electrodes of the capacitor that causes the stored electrical energy to be retained so long as the low-voltage power source remains active. A hybrid motor vehicle that includes a recoverable energy storage system, which recovers kinetic energy during operation of the hybrid motor vehicle, and a high-voltage energy storage device in accordance with the invention coupled to the recoverable energy storage system is also disclosed.

Dependent claims

A high-capacity electrical capacitor (“HCEC”), the HCEC comprising:

at least one capacitor having a pair of high-voltage high-power primary terminals and a pair of high-voltage low-power auxiliary terminals;
a main power source coupled to the high-voltage high-power primary terminals of the HCEC, wherein the main power source supplies electrical energy to the at least one capacitor;
and
an auxiliary power source coupled to the high-voltage low-power auxiliary terminals of the HCEC, wherein the auxiliary power source supplies a fixating electrical voltage to the at least one capacitor such that the at least one capacitor of the HCEC will retain any stored electrical energy so long as the fixating electrical voltage is supplied to the at least one capacitor of the HCEC.
